该软件通过专用LED控制输入执行循环电池电压电平测试。这个
电池为应用程序内存和实时时钟提供备用电源
断电。电池可通过PM8xx盖板或外部连接
连接到外部电池连接器。通过软件检查蓄电池电压。电压是公共的
用于内部和外部电池。因此，应拆下内部电池
使用外部电池时，由于两个电池并联会导致
大大降低了容量。

he software performs cyclic battery voltage level tests via a dedicated LED control input. The
battery provides back-up power for both the application memory and the real time clock during
power down. The battery is either accessible via the PM8xx cover panel or externally connected
to the external battery connector. Battery voltage is checked by the software. Voltage is common
for both the internal and external battery. For this reason the internal battery should be removed
when using the external battery, since having two batteries connected in parallel will result in
greatly reduced capacity.

Start-up in Redundant Configuration (CEX Bus Considerations)
The redundant configuration using CEX bus and CEX modules is supported along
with the processor modules PM861, PM864, PM865, PM866 and PM891.
At start-up, some things regarding the CEX bus and CEX modules have to be
considered when starting up a redundant AC 800M system:
• Without using BC810 units:
– At least one CEX module must be inserted, if there are base plates without
inserted modules in other positions.
CEX-BUS Provides extension of on-board communication ports.
Valid for PM861/PM864/PM865
RCU Link Connector Provides information and data transfer between Primary
and Backup CPU in redundant configuration.
Valid for PM891
